No. 853,522. Specification of Letters Patent. Patented May 14, 1907.

Application filed June 7,1906. 'Serial No. 320,565-

To all whom it may concerns Be it known that I, ,HA'RRIY W. SIiAVER, a

.citizen of the United States, residing at Pocahontas, 1 county ofv TazeWell,;State of Virginia, have invented certain new and use ful Improvements in Cable-Reel Apparatus for'Mining-Locomotives, of which the following is a specification, Theflpresent inventlon relates to mining locomotives and more part cularly to 'means for controllingthe flexible conductor-which isused'to'permit the locomotive to 1 gather "cars from the mining faces of the rooms in mines. .15

The-invention has-'forits object to provide a simple and inexpens ve arrangement whereby the flexible; conductor or cable is autoconduc'ton t inzftically paid-out or is wound upon areel. carried by the locomotive, as the locomotive travels away fromor-toward the fixed supply cause- .it to xert a winding torque upon the reel both when the loconiotiveis' traveling v away from. the fixed-conductor and when moving toward it;' As the locomotive fap proaches the-fixed conductor, the motor winds up the cable-and, by'causin'g the. meter-- to tend to run at. a speed which will wind u the cable faster than the locomotive is trave I r tor 9 is always energized in the same d1rec-' ing, a tension isplaced upon the cable sothat there is no danger of the cable becoming entangled or of being run overlb the locomo tive. As the locomotive trave sin the other" direction, the motor is pulled backwardby the 'cableland the torque of the motor'mai-n tains the cable taut;

The invention will bemore fully understood and its advantages will more clearly. appear from the following detailed descrip tion taken in connection with the tion, a portion of the frame being broken away for the purpose of showing the cable reel motor; Fig. 2 shows in, cross-section a sat sfactory formof reel; and'Fig- 3 is adiathe locomotive.

reel motor but-also 'theprop'elling motor of preferredmype; 2 is a cable reel of any usual or preferredl type. Briefly stated, this reel c'omprises arotatable member 3 mounted upon a )ase or support 4arranged on the top of the.

locomotive and having one end of a flexible conductor or cable'5 secu red thereto and elec 'trically connected .to abranch conductor 6- which leads to the-control apparatus. At the free end of the. cable 5 is any suitable means -7 for securing this end. of the conducv tor'to the fixed supply conductor 9 is'a inotor,.p'referablya series'motor, having driving connection with llhG'IllOVStblO inen1 I ber of thereel; This connection may take any desiredor preferred form,- a convenient arrangement comprising a chain 10 passing zover sprocket-wheels 11 and 12 mounted r espectively on the motor-shaft andupon a s ort shaft 13 jour'naled in a fixed. support and provided at one end with a pinion 14 adapted" to inesh'. with a gear-wheel 15 secured to the 'mernber'3. The driving connection is a permanent one, the present'inventioi'1' -obviating the rlec'essityof clutch apparatus of any kind for changing the connection between the motor-and thereel when the locomotigye'is turned end for end.

In accordance with my invention the inotion independently of the direction ofmovement of the locomotive being of course cut out whenthe locomotive is receivingvcurrent In Fig. 3 I have shown neansi for control- 20, is the usual reverse ing switch for the motor 17. -.lVhen the ca- -'ble is in use the switch 23 is moved to the position shown, disconnecting trolley 16 from and connecting conductor 6,-and therefore the switch 23, as .shown,comp letes the'cir'- cuit'between the motor 9 and the cable 5. f

The in is to'permit t circuit of-the drivi' position or in 'afi'y'operative oe locomotive to coast withthe motor broken but with reel motor energized; It is of course-understood that instead of a single inotori17,
